Fucking brilliant! The notion that all those who came before western civilisation's recent arrival were benighted savages swinging from trees and had nothing of value to offer our science or larder is astonishing in its breadth of ignorance. Yeah, they swung from trees, all right- trees their great grandparents planted!
This isn't the only example of long time scale food forestry by indigenous peoples that I've heard of. Another involved Mayan aquaculture- at high altitude. The adaptation to local climate conditions and productivity of the system was such that modern agricultural techniques still don't come close to matching it!
This tells me that we indoor growers are just scratching the surface of what's going to be ecosystems embedded in environmental control systems that feed, shelter and purify air for people- inside boxes. If that sounds a little depressing, consider that as long as our box has power, it can go anywhere... and it better, if our kind is to survive its own fitful technological adolescence.
